And just like true ride-or-dies, they dedicate throwback posts to each other on their birthdays. Here's Miranda's for Jennette last year:

"Ooooh here she comes! Watch out boys she'll chew you upppp! Soo it's @jennettemccurdy's birthday today! The apple of my eye, the peanut butter to my jelly, the cheese to my crackers, the protective screen to my iPhone 6s, the cowboy with a mustache to my idiot farm girl! I love her and so does everybody else. She's been making life better since I met her over 10 years ago. She's honest and hilarious and she makes me wanna be as funny and perfect as she is! Here's to the best birthday yet! ❤️💕🎈☺️"

And then here's the super-sweet message Jennette wrote for Miranda:

"Happy birthday to @mirandacosgrove. We met when we were just two little beans. She was sipping Coca Cola from a bottle and I was wearing camouflage zip-off pants from Limited Too. . . Needless to say, I thought she was the coolest person ever.

10 years and a million memories later, and I still think Miranda is the coolest person ever. You'll never find anyone with a bigger heart, a sharper sense of humor, or a better sense of authenticity in a sometimes bullshit world. (Jk the world is perfect! Peace! Love! Daisies!) ... Miranda is the best, and if there was a government-recognized legal union for friendships, I would enter one with her.

Send Cosgrove some bday love, BEANOS."

Basically, they're the ultimate BFF goals and proof that some child stars can make the transition to adult friends and live happily ever after.
